C# 3.0 and LINQ
I just watched an exciting Channel 9 video about the future of C# 3.0, featuring Anders Hejlsberg. It highlighted some game-changing features, including extending classes with new methods without derivation and the introduction of Lambda functions. One particularly cool feature is the addition of LINQ (Language Integrated Query), which extends IEnumerable objects with SQL-style operators. I'm still exploring how I can use this in my own projects, but it looks incredibly promising!
